' Application filed October 23, 1924. Serial No. 745,278.

The invention relates to concrete 'wall constructions and its primary object is to provide an improved method of, and means for, forming grooves having constricted entrance in the concrete wall, and which are adapted for the wall ties. The invention consists in theseveral novel features hereinafterset forthv and more particularly defined by'clai ms at the conclusion hereof.

In the drawings :Fig; 1 is a horizontal section showing aform in position in a concrete wall. Fig. 2 is a similarview, showing one of theformsections removed therefrom. Fig. 3 is a modified form of the invention, in which the formis adapted to produce a wide groove and is formed of three sections. Fig. 4 is an, elevation, show ing the manner of anchoring brick facing to a concrete wall by means of ties held in the grooves. Fig. 5 is an elevation, showing theme of brick ties and wide grooves for tying a brick'facing to the concrete wall. Fig. 6 is a section on line5-5 of Fig. 4:.

Fig. 7 is a section on line 77 of Fig.

Fig. 8 is a perspective, and Fig. 9 a horizontal section of the tie shown in Figs. 4- and 6. Fig. 10 is a perspectiveshowing the groove-forms in the concrete wall. Fig. 11 isa perspective of the wall after the forms havebeen removed, and a tie held in the groove.

In the construction of concrete walls, it

has heretofore been proposed to use channelled metallic members embedded in the concrete wall to provide grooves for securing ties or anchors for a brick or other facing to the concrete wall. This has been found to increase the costof erection, be-' cause of the high cost of the steel liners.

The primary object of the invention is toprovide a method offforming dove-tailed grooves or grooves with constricted entrances in the concrete wall 1n such a man nor that the liners may be dispensed with. This object is attained by providing a form composed of separatestrips which are adapt ed to produce grooves of the desired shape in the concrete wall and are removable therefrom when the concrete has set, thus dispensing wit-h the necessity of leaving any metal in the grooves in the concrete wall.

In the form of the invention shown and illustrated in Figs. 1 and 2, the form is composed of longitudinally extending sections 10 and 11. Each of these sections comprises an inwardly flared-side 12, a backflange 13 and a front flange 14. The back flanges'13 are extended to meet centrally of the grooves; The sides are flared inwardly, so that the entranceto the groove will be constricted to adapt it for holding ties therein.

The back flanges 13 are extended to meet on a central line of the groove. The front flanges 14 are usually attached by nails 15 or other suitable means to the wooden strips 16 which'are adapted to form the outer face of the concrete wall 17. lVhenthe concrete has been poured to form the wall, an integral mass thereof will extend around the backiandsides of the sectional form; The latter is formed of strips of convenient length for handling. In practice, strips four feet in length have been found to operate f satisfactorily. These strips are laid end to end to form continuously extending grooves of any desired length or height. When the concrete has set around thegroove form, the form boards 16 will be removed. Thenithe section 11 of the form can be removed'from the wall, as indicated bydotted lines inFig; 2. To permit this to be done, the sideis formed so that when it is swung about a point at the meeting edges between'the sections, the side 12 will be free to swinginwardly from, and clear'the contiguous face of, the groove side in the concrete 17. After the section 11 has been removed, the section 10 may be similarly removed. In removing the form, the sections are swung or-m-oved transversely ofthe groove. The forms could not be practically separated by longitudinal movement in the groove. has been removed, a groove with a back 19, rearwardly flaring sides 20, conforming to the outer faces of'the' form-sides 12, and a groove 21 will be formed in the'concrete When the form wall,- and this groove may extend thefull length or height of. the wall, if desired.

1 The flanges 14 will form arecess at thesides tend transversely across the groove 25 in the concrete. The sides oi said groove are rearwardly flared, as previously described, so that the ends of the anchors 24- will interlock therewith and he held thereby.

In Fig. 3, there is illustrated a modification, which is more particularly adapted for forming grooves of considerable width. In this form of the invention. the groove form consists of sections 10 and 11, similar to those previously described, and an intermediate bacl: plate 13". The latter has its margins bent backwardly, as at 13, to back lap the inner margins of back members l3 and is provided with lugs 13 to form an interlock between the form sections, by which the intermediate section 13 will be supported from the sections 10 and 11, the latter being supported from the tormboards 16, as hereinbetore. described. After the concrete has been poured around the form and has set, the form will. be removed from the wall. by first swinging the section 11 transversely, as shown by dotted lines in Fig. 3, then similarly removing the section 10; and then removing the intermediate section 18. The intermediate section can be removed forwardly when both of the sections 10 and 11 have been removed. hen this form has been removed from the wall 17", the latter will be provided with a groove 25 of any desired length, with a constricted entrance, so that it will be adapted to hold wall anchors.

In Fig. 5 and 7, there is illustrated a brick facing 22 and obliquely laid anchor bricksQL-l which are embedded in mortar and extend obliquely into the groove 25*" to interlock with one of its sides.

The invent-ion exemplifies a method for forming, in concrete walls, dove-tahed grooves or grooves having constricted entrances to interlock with wall anchors, in which ametallic lining is dispensed with, the metallic terms being adapted to be removed transversely from the grooves. in

this manner, the cost of forming these grooves is greatly reduced, because the forms are adapted for repeated use. The term used makes it possible to remove it, even though the ends of the grooves should be closed, as occurs in some instances.

The invention is not to he understood as restricted to the details set 't'orth, since these may be modified within the scope of the appended claims, without departing tlirom the spirit and scope of the inveiuion.

Having thus described the invention, what l claim as new and. desire to secure by Letters Patent, is:

In concrete wall construct-ion, the combination of a term for a concrete wall, and a lorm supported by the \vall-l'orm and :ulapted to form a groove for anchors in one taco oi the "all, said last mentioned 'lorm consisting of separately tormed metallic sections having flared sides for producing a constricted entrance in the groove, said sections being removable individually and transversely from the groove through the constricted entrance, a ttcr the concrete has set.

2. In concrete "all construction, the coml ination oil a term for a concrete wall, a form supported by the wall-form and adapted to term a groove 'lor anchors in one taco ol': the wall, said lastmentioned torm consisting of separately l'iorincd n'ictallic sections, each oi said sections comprising an integral side, back portion, and front flange, the sides oi said sections being liar l to produce a constricted entrance in the groove, and means connected to the trout flanges ot the sections for tcnniorarily securing the latter to the wall, form, said sections being removable imlividually and transversely from the groove through the entrance, after the concrete has set and the portion of the wall torm to which the sections are attached is removed.

3. In concrete wall construction, the combination of a form :lor a concrete wall, and a metallic groove-torm supported by the \vall-jtorni and consisting oil. a pair of sections having flared sides tor 'lorming the sides of the groove and a separately lormed intermediate back section between the side sections and for spacing the latter apart, all of said sections being individually removable from the groove, after the concrete has set.
